Abstract
The invention provides a production process for rapeseed oil; the rapeseed oil is obtained through a step of removing seed coats through scalding, a low temperature pressing step and a refrigerated centrifugation step. According to the production process, especially in the refining process of the rapeseed oil, no chemical reagents are added; as refining is performed by adopting a pure physical method, the obtained rapeseed oil reserves specific active substances, such as Vitamin E, of rapeseeds, and is free of residual solvent and pollution, high in safety and high in oil product quality. As no chemical reagents are added in the refining process, no chemical reagents remain, and the rapeseed oil can be used as excellent high-end edible oil and cosmetics or pharmaceutical additives; the rapeseed oil extracted by the production process provided by the invention smells fragrant and is particular in flavor, can be widely suitable for cooking various foods and dishes, has higher nutritive value and a health-care effect, reserves high-antioxidant active ingredients, and is especially suitable for being popularized in the technical field of small-batch production of special oil.
Description
Technical field
The present invention relates to a kind of method of the rapeseed oil that produces oil, art, biological and new medical technology, modern agricultural technology, agricultural-food intensive processing and modern accumulating: agriculture and forestry product and extraordinary enhance productivity are processed.
Background technology
Rapeseed oil is one of traditional edible vegetable oil of China; be of high nutritive value; be easy to absorption of human body; its main component is triacylglycerol; in addition also containing micro-nutrient compositions such as polyphenol from rapeseed, tocopherol, plant brassicasterol and polyphenol from rapeseed; these nutritive ingredients have multiple physiologically active and nourishing function, and its stronger anti-oxidant activity to vegetable seed oil oxidation stability also
Play positive provide protection.
Traditional rapeseed oil manufacture craft is divided into mechanical expression and solvent extraction two kinds, mechanical expression technique adopts physical impact mode, the method that grease is squeezed out from vegetable seed, be divided into again hot moulding and cold press two kinds, general hot moulding meeting havoc vegetable seed cell, can destroy the nutritive ingredient in oil after high temperature, reduce nutritive value and the quality of rapeseed oil, and pressed oil oxidative stability is not very desirable, and oil yield is low, and in cake, Residual oil is high.
Therefore, further investigation and exploitation rapeseed Processing technology, promote rapeseed oil quality and nutritive value, improve the oil yield of vegetable seed, improve vegetable seed oil oxidation stability, thus promote that China's rape processing technology progress and Rape industry sound development become very important and urgent task.
In order to solve Problems existing in current rapeseed oil production process, retaining original nutritive ingredient such as Semen Brassicae campestris acid and vitamin-E in rapeseed oil to greatest extent, reducing and avoid the formation of trans fatty acid, guarantee the nutrition of rapeseed oil product, safety; Improve quality product and yield, reduce energy consumption and waste discharge, achieve the impairment synergy that rapeseed oil is produced.Be badly in need of a kind of rapeseed oil production and processing method.
Summary of the invention
The object of the present invention is to provide the rapeseed oil production method of a kind of easy, nutritive value and health care, rational technology.
Technical scheme of the present invention is achieved in that and comprises the steps:
A, airing is carried out to Semen Brassicae campestris, control water ratio 3%-5%;
B, the rape seed of A, process is added in the boiling water of temperature 90-100 DEG C, amount of water be the 4-10 of rape seed amount doubly, soaks after 3-5 minute and hot water is discharged, draw the Semen juglandis cathayensis in cool clear water flushing jacketed kettle with hydraulic giant, remove attached skin; Repeated multiple times;
C, the rape seed hydropress of B, process is added extrusion crude oil; Rape seed is made cake and puts into hydropress, often squeeze and throw cake 20-25 block, every block is about 4-6kg, equably pressurized hydraulic low pressure, when making pressure be pressed onto 110-120MPa, low pressure is transferred to high pressure, and uniform pressurization is to during 280-300MPa, during squeezing, can not be too fast, in order to avoid cake slag oozes out; Obtain crude oil, weigh, calculate oil yield, for subsequent use;
D, frozen centrifugation, crude oil to be positioned in the environment of 1 ~ 5 DEG C freezing 30 ~ 90 minutes, the oil after freezing being positioned over rotating speed is in the high speed freezing centrifuge of 14000 ~ 18000r/min centrifugal 10 ~ 30 minutes again, removing impurity, put into temperature 60 ~ 80 DEG C of vacuum chambers and vacuumize 8 ~ 12 hours, obtain rapeseed oil.
Compared with prior art the inventive method tool has the following advantages: (1) the invention provides a kind of minimizing technology of Semen Brassicae campestris underwear, production for high quality oils rapeseed oil provides High quality processing raw material, facilitate the technical progress of Semen Brassicae campestris secondary industry, improve added value of product; (2) the present invention is in the refining process of rapeseed oil, do not add chemical reagent, adopt pure physical method to carry out refining, the rapeseed oil of acquisition remains the distinctive amino acid of Semen Brassicae campestris and vitamin-E isoreactivity material, and no solvent residue, pollution-free, security good, oil quality is high.Owing to not adding any chemical reagent in extractive process, without chemical residual reagent, can be used as fabulous high-end edible oil and makeup or pharmacy additive.Edible with for tonifying the liver and kidney in medicine, controlling nocturnal emission with astringent drugs contracting urinates, relaxes bowel, improving eyesight is different from seed benevolence chemical constitution according to the underwear of Semen Brassicae campestris; (3) the present invention utilizes physical cold Technology in Pressing, make there is no organic solvent residual in product, the crude oil color and luster that cold press simultaneously goes out is more shallow than traditional hot pressed oil rapeseed oil, do not need through coming unstuck, alkali refining, decolouring, deodorization process, thus the loss such as natural nutrition VE is few, and also not producing the objectionable impuritiess such as trans fatty acid provides; (4) the present invention utilizes frozen centrifugation technology technology, removes impurity fast, shortens the oil expression time, increase work efficiency; (5) in the high-quality grease that the present invention produces, because be rich in the natural antioxidantss such as natural VE, do not need in grease storage process additionally to add oxidation inhibitor.
Further restriction, in order to obtain the Semen Brassicae campestris being applicable to squeezing, adopt the boiling water adding temperature 100 DEG C in B, step, amount of water is 7 times of rape seed amount, soaks 4 minutes.
Further restriction, in order to reach best separating effect, the rotating speed of the high speed freezing centrifuge adopted in D, step is 17000r/min.
The invention provides the rapeseed oil production method of a kind of easy, nutritive value and health care, rational technology, can produce for short run special oil and technical support is provided, be suitable for promoting in edible fat production technical field.
